What is the peak-to-peak voltage of 120V?
170V
Is AC voltage peak-to-peak?
Peak-to-peak amplitude is the total height of an AC waveform as measured from maximum positive to maximum negative peaks on a graph. Also known as the “equivalent” or “DC equivalent” value of an AC voltage or current. For a sine wave, the RMS value is approximately 0.707 of its peak value.
What does the RMS tell you?
They help to find the effective value of AC (voltage or current). This RMS is a mathematical quantity (used in many math fields) used to compare both alternating and direct currents (or voltage). Hence, taking an average value (mean) I20/2 and then determining the square root I0/√2 would give the RMS.
What is true RMS on a multimeter?
True RMS responding multimeters measure the “heating” potential of an applied voltage. Unlike an “average responding” measurement, a true RMS measurement is used to determine the power dissipated in a resistor. The power is proportional to the square of the measured true RMS voltage, independent of waveshape.

What is the easiest multimeter to use?
Our top pick, the Fluke 115 Compact True-RMS Digital Multimeter, has the features of a pro model, but it’s easy to use, even for beginners. A multimeter is the primary tool for checking when something electrical isn’t working properly. It measures voltage, resistance, or current in wiring circuits.
Why do I need a true RMS multimeter?
Depending on the type of AC waveform, the reading might be up to 40% low. If you need to measure the voltage or current of AC signals that are not pure sine waves, such as when you’re measuring the output of adjustable speed motor controls or adjustable heating controls, then you need a “true RMS” meter.
What multimeter has the highest safety rating?
Fluke’s “ABCs of Multimeter Safety” explains CAT Ratings Within a category, a higher voltage rating denotes a higher transient withstand rating, e.g., a CAT III-1000 V meter has superior protection compared to a CAT III-600 V rated meter.
What does Cat 3 mean on a multimeter?
A higher CAT number refers to an electrical environment with higher power available and higher energy transients. Thus, a multimeter designed to a CAT III standard is resistant to much higher energy transients than one designed to CAT II standards.
What is the difference between CAT II and CAT III multimeter?
CAT II-rated test instruments cover the local level of circuits for fixed or non-fixed power devices. CAT III-rated test instruments can withstand the transient voltage range found on most distribution circuits. These instruments are used primarily on fixed primary feeders or branch circuits.
